Just a guess: Because of all the coal around this area, I would suppose that sulfide minerals, especially pyrite (iron sulfide) would be common. Some sphalerite (Zn, Fe sulfide) has been found in Lucerne county. Some rozenite (hydrated Fe sulfate) has been reported from Jeddo Highland coal mine in Hazleton.
"Sulfide minerals typically occur in coal beds as well as in strata overlying and underlying the coal. Weathering and aqueous dissolution of the sulfide mineral oxidation products, including dissociated sulfuric acid and metals (e.g., Fe, Mn, Al), produces surface and groundwater degradation."

"By far the most serious environmental problem caused by abandoned mines is polluted water. It happens when rain comes into contact with a surface or underground mine and interacts with the mineral pyrite, better known as fools' gold, to form sulfuric acid. The toxic brew discharges into streams and rivers, choking off plants and wildlife and coating streambeds with iron hydroxide, tinting water yellow, red or orange. Aluminum, manganese and other metals also leach into the water.
Old mining operations have polluted about 4,000 miles, or 5 percent, of the rivers and streams in Pennsylvania, officials estimate. The west branch of the mighty Susquehanna River is dead for its upper 70 miles; 1,000 miles of its tributaries are likewise lifeless. The Jeddo Tunnel, an engineering marvel drilled through miles of solid rock to drain deep mines in the Hazleton area, discharges 40,000 gallons of polluted water a minute into the Little Nescopeck Creek -- the largest such discharge in a state full of them."
